More than a dozen teenage school kids were hospitalized when their bus collided with an ambulance in Brooklyn on a snowy Sunday night, authorities said.

The FDNY ambulance was responding to a call of an emotionally disturbed person at around 9 p.m. when it crashed into the front of a Yeshiva Machzka Hadas bus in the intersection of Fort Hamilton parkway and 51st Street, authorities said.

Eighteen boys returning from an after-school program were on the bus, witnesses said.

“I was in my bed and I heard a big explosion,” said witness Rogelio Rodriguez. “I saw a lot of people running away from the bus.”

The teens on the bus and the two EMT workers were taken to Lutheran and Maimonides Hospitals for minor injuries, authorities said.

It is unknown if slick road conditions factored into the accident.

“I’m sure weather played some factor but it is still under investigation,” said FDNY Deputy Chief Alvin Suriel at the scene.
